Product Description
The Digital Small Sample Viscometer models YR05840, YR05841, and YR05842 are designed to offer unmatched precision in measuring viscosity of small samples. These instruments are engineered to cater to a wide range of viscosities, making them ideal for diverse laboratory applications. Whether in a research laboratory or an industrial setting, these viscometers provide reliable and consistent results aligned with modern scientific demands.
The instruments boast an impressive measurement range, with the YR05840 model covering viscosities from 6.4 mPa.s to 2M mPa.s. The YR05841 model extends this capability from 12.8 mPa.s to 4M mPa.s, while the YR05842 model accommodates an even broader range from 51.2 mPa.s to 16M mPa.s. Such versatility ensures that users can handle samples spanning a wide spectrum of fluid characteristics.
Enhancing the operational flexibility, these viscometers feature a rotor system inclusive of rotors numbered 21, 27, 28, and 29# as a standard configuration, with an optional ultra-low viscosity adapter (rotor No.0) and a separate heating furnace available for added adaptability. A total of 18 speed settings are available, ranging from 0.5 to 100 r/min, providing users the ability to tailor measurements precisely to their requirements.
For those requiring stringent controls on test accuracy, these viscometers promise a test error margin of ±2% for Newtonian liquids and a repetitive error of ±1%. Furthermore, the temperature control precision stands at a remarkable 0.1℃, demonstrating their commitment to delivering high-precision data.

Frequently Asked Questions
What is the difference between the YR05840 and YR05842 models?
The primary difference lies in the measurement range each model offers. The YR05840 measures viscosities from 6.4 to 2,000,000 mPa.s, while the YR05842 can measure from 51.2 to 16,000,000 mPa.s. This makes the YR05842 suitable for more viscous samples compared to its counterparts.
Can these viscometers handle non-Newtonian fluids?
Yes, while the test error and repetitive error values are specified for Newtonian liquids, these viscometers can indeed handle non-Newtonian fluids. However, additional considerations regarding fluid properties and testing conditions should be made to ensure accurate measurements.
Is it possible to upgrade the temperature control range?
Yes, the temperature control feature is upgradeable, with options available to extend the upper limit from 250°C to 300°C, providing greater flexibility and scope for various testing environments.
Advantages and Disadvantages
One of the most significant advantages of these viscometers is their capacity to deliver precise and reliable data across a remarkably wide range of viscosities. The integration of robust configurations, multiple rotors, and seamless RS232 interfaces elevates their usability and adaptability in professional settings. The ±2% test error margin ensures consistency and reliability, critical for complex evaluations.
Nevertheless, one potential downside could be the initial cost investment, which may pose a challenge for smaller laboratories with budget constraints. Additionally, users must be well-versed in viscometry for optimal use, which may necessitate training for novices.
Product Use in the Field
In practical scenarios, these viscometers excel across numerous fields including pharmaceuticals, petrochemicals, and food industries. Scientists and engineers often employ these devices to ensure quality control and formulation verification, playing a crucial role in the standardization of processes and products. The ability to manage various speed settings thus aligns with the dynamic needs of field applications.
The optional heating furnace allows for precise temperature control, essential for samples that demand specific thermal conditions during testing, thereby making these instruments indispensable in R&D environments.
